Specs-stock displacement

Anyone have them on OEM rings, liners, pistons? Any specs and PN are appreciated

haibeck and some other tuners, the gm parts guides too. but the gm stuff is ultra pricey and made out of unobtanium anyway.

I know of a real nice rotating assembly. I couldn't give it away so I traded it for some 5 spokes.

you should just put the 4" liners and run a better piston anyway. cheaper and better. the 368 is a nice motor.

Been thinking about that for next year when I tear it down (cant afford to wipe me arse right now). I was at a friend of mines shop who owns a large engine rebuilding operation and wanted me to get the ring/liner/piston info as I had told him about our unobtanium problem

. He claims hes familiar with the motors and is sure he can locate a ring man. at least if I could do a little leg work, as hes a pretty busy guy.
Worth a shot.

Ring size would be great or dimensions/PN for pistons. Hes well aware of LA liners.
Bore size, ring gap would be great

No rings my butt
